Sound familiar?
The invoicing problems independent plumbers actually face.
📋
Estimates and final invoices are disconnected
You write up a quote before the job, then manually recreate it as an invoice after. Every job you're retyping parts lists, labor descriptions, and pricing from scratch.
💧
Parts markups get lost in the shuffle
You buy the part, markup for installation, and charge labor - but tracking that across 10 jobs a week on paper means you're constantly undercharging or forgetting line items.
🔧
Flat rate vs. time-and-material billing both feel clunky
Some jobs are flat rate. Some are time-and-material. Some are a mix. Your current invoicing doesn't handle both cleanly, so you're explaining the bill to every customer.
⚡
Emergency calls don't give you time to invoice properly
2am pipe burst. You show up, fix it, the customer is grateful - but you leave without an invoice because you didn't have your billing system in hand. You follow up later. They've calmed down. Payment takes longer.
💳
Customers can't pay on the spot
You hand them a paper invoice and tell them to mail a check or Venmo you. Some do. Some don't. You're chasing checks when you should be at the next job.
📊
Outstanding invoices across multiple jobs are hard to track
Running 8 jobs this week and last week. Which invoices are paid? Which are overdue? You don't know until you dig through papers or emails.
The fix
A billing workflow built around how plumbing jobs actually work.
📋
Estimate-to-invoice in one click
Send a detailed estimate before the job for customer sign-off. When the work is done, convert the accepted estimate to a final invoice in one click. Every part, labor hour, and flat rate fee carries over - no retyping.
💧
Itemized line items: parts, labor, service fees, markup
Build invoices with separate line items for materials, labor hours, flat rates, disposal fees, and markup. Each job's billing is transparent and defensible.
🔧
Flat rate and time-and-material in the same invoice
Mix flat rate line items with hourly labor on the same invoice. Bill exactly the way the job actually went - no awkward explanations to the customer.
⚡
Invoice from your phone before you leave the driveway
Pull up WaffleInvoice on-site, build the invoice, and text the customer a payment link before you start the truck. The payment window is open while they're still satisfied with your work.
💳
Customers pay by card or ACH from the invoice link
Share a payment link via text. Customers pay by credit card or ACH bank transfer directly from their phone. No checks, no Venmo, no chasing.
📊
